n/IPROVBMENT IN SPECTACLE-PRAMES. w The Bchedu1e referred to in these Letter-5' Patent and making part of the same To all whom it may concern.-

Be it known that I, Ormuxusy BUoKLnY, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in spectacleFrames; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be afull, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent in- Figure 1 an edge view looking down upon the joint;

Figure 221. front view, showing aportion of the frame and end piece;

Figure 3, a sectional view through line a: a of Figure 4, a vertical section on line .2 of fig. 1

Figure 5, a top view; and in Figure 6, an edge view of the temple.

This invention relates to an improvement in the construction of the joint of spectacle-frames; the object being to construct a joint with a single screw with a long end piece, as in the better class 'of glasses, and so as to give an increased: support to the temple on the joint, and at the same time simplify and improve the construction; and

The invention consists in constructing the temple from a piece of sheet metal, with the part which forms the joint thrown sufiiciently far inward to give the requisite spread, and in perforating the said joint part with a diameter larger than the screw which secures the two parts of the end piece together, and milling the surface between the two parts, so as toi'orm a. bearing in the end piece for the turning part of the temple, whereby I am enabled to dispense with the use of the rivet, and yet aiford a larger and better bearing for the temple without in any way affecting the screw.

A is the temple, shown detached in figs. 5 and 6, and is cut from sheet metal of the required thickness, so that no drawing is necessary, at d the turning part B formed thereon turned out of line with the temple, so as to give the requisite spread to the temple, and so as to form a bearing-shoulder, a, the turning part being perforated as at ll, with a diameter larger than the screw 1' of the end piece.

1 G is 'the end-piece, formed in two parts, each respectively fixed to one end of the frame, as seen in figs.

that the portion of metal n within the circular channel t corresponds to the perforaton (I, and the channel tto the metal without the perforation (1, so that the turning pnrt'B will lie and freely turn in the channel -i-. I

By this construction it will be observed that the metal through which the screw passes is preserved entire, so that the full thread may be cut in one part, and the other part counterbored for the head, in prec-iscly the same manner as where a rivet is used as a pintle for the temple to turn upon.

The end piece projects out as at 1), corresponding to the shoulder a on the temple, so that when the temple is turned, as in fig. 1, a strong bearing is formed, at the same time giving a neat and finished appearance both to the end piece and temple.

By this invention both the construction of the end piece and temple are very much simplified, as the usual swaging and milling of the temple is entirely avoided, the extra rivet in the temple also dispensed with, and no additional work made thereon.

The millim of the endiece to receive the turnin a: P a

part of the temple may be cntirelyin one part of the end piece, or a portion in both parts.

I claim as my invention- 1. The channel 2 formed in the end piece, so as to leave the hearing it around'the screw f to receive the turning part of the temple, substantially as set forth. 2. The temple .A formed complete from sheetmetal, with the turning part'B thrown to one side to give the requisite spread to the temple, and at the same time to form the shoulder a, combined with the end piece constructed as described, with the projec-' tion I; to support the shoulder a, as herein set forth.
